OK, it's dated; but it's also one of the very few plant names that I like enough to use. When I was a kid I thought that Heather and Erica would be wonderful names for twins; I've got over that, but it's still got a happy, lively, outdoorsy vibe that's very attractive.
Never heard of Degrassi, and I doubt if the scriptwriters (?) have ever heard of me ... I wouldn't be surprised to encounter real-life ones, somewhere in the world.
